and what flywheel and clutch do i use..thanks for your time

 

It will, and I used my existing 91 Si flywheel/clutch combo when I did mine.

 

badass! thanks

 

im lookin on e bay and i found clutches that are 21 splines and 20 splines and even one with 23...the si's are 21 right...and would a 7.5 pound flwheel be too light...thanks again

 

Clutch needs to match transmission (considering it's the transmission side with the splines)
flywheel is a matter of preference. i just got my stock one shaved and resurfaced at a local shop.
You just have to ask yourself: what is better, OEM cast iron that is tried and true, or aftermarket made out of aluminum? Do you want to be taking it apart again if it fails?
the difference in splines is 88, 89-00. 88 is the odd one.
90-91 has a bigger clutch opposed to 89.

 

hmm.well i know i have a 89 si and the trans is a cable trans...so i have a 21 spline assuming i have the original trans?

 

go count the splines
or just buy a clutch for the 89.
i'm surprised you didn't ask what pressure plate to use....

spoon-feed: 88 = 21, 89-00 = 20

 

the guy from the parts store said its a 21 spline..im asking cuz last time i replaced my clutch i had to get the hydro style clutch with a cable style throw out bearing..

 

GO COUNT THE SPLINES YOURSELF.

 

the cars not takin apart..tryin to gather everything be4 hand

 

dude it's your car the guy at the parts counter doesn't know ****. 88's are the ONLY year that have a 21 spline clutch. 89's use a 20 spline clutch but are the smaller 200mm diameter, 90-91 use a 20 spline clutch that's like 210mm's. look in the faq for the thread that tells you how to identify your transmission
